Global CO2 levels hit record high, scientists warn

Atmospheric carbon dioxide concentrations reached a record high, exceeding 430 parts per million for the first time, according to NOAA and Scripps Institution of Oceanography. This marks another grim milestone in climate change. Scientists measured a May average of 430.2 ppm, a 3.5 ppm increase from May 2024. This continues a trend of rising CO2 levels, with the 2024 average increasing faster than any previous year since records began in 1958. The new record follows a UN report warning of potential temperature increases. Experts note the significance of these rising levels and the need for action to stabilize greenhouse gas concentrations.
